I just got done installing my new flywheel (5-speed swap) and when I was pushing on the flywheel the whole crank moved towards the front of the car. I understand you should have a little endplay, but I think I have a little too much. I just put the 331 stroker engine in this past summer. I only have like 6500 miles on it. What could cause this. I just hope this isn't a huge deal. I can't afford to tear apart the whole engine. Thanks for any help.
